I've got a '91 Legacy and I'm rebuilding the A/C system. I can't seem to find in any manual (or anywhere else) the amount of compressor oil I should re-introduce into this system. It's a Calsonic V5-15 comprssor. I understand that I should "split" the oil between the compressor and the dryer but still don't know how many ounces... Can about help?

I did mine last year-a 91 as well. I replaced rec drier and compressor that had locked up. I believe the tech at the shop where i took it to to be vacuumed and charged told me to put in 6.5 oz of oil, about 2-3 in comp, 2 or so in rec drier , and split rest between evaporator and condensor, not super critical on the distribution. Mine had already been converted from R12 on previous failure, but he stressed to use ESTER oil if converting from R12 as it would mix with any traces of the old oil that was used with R12.
